Storage reservoirs beyond a lake district as secondary habitats for caddisflies (Insecta: Trichoptera) in an area of karst origin (SE Poland)

“…By managing the vegetation, one can maintain the reservoirs (or parts of them) in various stages of succession: the effects of this have been positive in the case of fish ponds (Buczyńska et al, 2007) and peat pools (Wildermuth, 2001). The present work, like the survey of the macrofauna of three shallow lakes in China (Hu et al, 2016), has shown that particular assemblages are associated with a specific level of productivity in a water body. This knowledge can be used to detect rising levels of eutrophication, one of the more serious problems affecting standing waters, which are also detrimental to biotic communities (Strayer and Dudgeon, 2010).…”

“…Weatherhead and James (2001) found positive relationships between Trichoptera and macrophyte biomass in the littoral zone of nine New Zealand lakes, and Tolonen et al (2003) discovered that Trichoptera in three lakes in Finland were significantly affected by macrophytes. In general, macrophytes in shallow lakes support more ecological niches, which in turn allows more species to coexist (Hu et al, 2016). The elodeid zone of lakes is more stable, with fewer incidental species and a large number of limnobionts in comparison with the helophyte zone (Czachorowski, 1998).…”

“…Still, very little is known about these complex relationships in shallow artificial water bodies. Most papers relating to the invertebrate fauna of this kind of environment have focused on the effect of factors acting exclusively in the water and usually describe these relationships on the basis of particular higher order taxa (order or class) or selectively identified invertebrate species, without taking account of their life histories (Samways et al, 1996;Prus et al, 1999;Poznańska et al, 2009;Hu et al, 2016;Fadilah et al, 2017). However, the location of a reservoir (woodland area, peatbog, farmland), its age as well as the manner and intensity of its management also exert a certain influence on the quantitative and qualitative structure of the macroinvertebrates (Miguel-Chinchilla et al, 2014; Buczyńska et al, 2016;Fadilah et al, 2017).…”

Has Submerged Vegetation Loss Altered Sediment Denitrification, N2O Production, and Denitrifying Microbial Communities in Subtropical Lakes?

“…For instance, Pan et al () revealed that macroinvertebrate diversity declined with increasing eutrophication in Yangtze lakes, because of the gradual disappearance of aquatic vegetation that provided food sources and habitable area for epiphytic animals. However, Hu et al () indicated that the total abundance of sediment microinvertebrates was significantly higher in the algae‐dominated lakes than in the macrophyte‐dominated lakes in eastern China. In this study, the diversity and abundance of denitrifying microbial communities did not differ significantly between macrophyte‐rich and macrophyte‐free lakes (Table ).…”
